Registration will open for a limited number of spots for active-duty military on February 19. Lottery registration for the public will occur from February 23 through March 15.

This year's registration, held in March, was beset by technical issues. Although the marathon's field filled in a record two hours and 27 minutes, race officials expressed displeasure with the user experience potential entrants encountered, leading Active to issue an apology in April.

"Race IT will provide MCM with the peace of mind that their heavy traffic will be handled when registration opens and their participants will be in capable hands," today's announcement said.

In February, registration for the Chicago Marathon, also through Active, was suspended on the first day of registration because of what were termed "technology system issues" on Active. Registration via Active never reopened, and the marathon filled its remaining spots with a lottery.

In May, Active's CEO and board chair resigned. Earlier this month, Vista Equity Partners, a private equity firm, was reported to be buying Active for between $900 million and $1 billion.
